WASHING-MACHINE.

Specification of Letters Patent. Patented Nov. 26, 1 918.

App llcatlon flled August 7, 1918. Serial No. 248,789.

To all whom it may concern:

Be it known that I Rmm J. CLARK, Jr., a citizen of the United'S'tates, residing at Youngstown in the county ofMahoaing, State of Ohio, have inve'nted'a new and useful Washing-Machine; andgI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it appertaius tomake anduse the same. I

The present inventlon relates to certain new and useful improvements in washing machincsyand has-for its object to provide a device of this character which embodies novel features; ofhtiiastructron whereby clothes can be thoroughly and quickly cleansed by mechaniealnieans without injury to even delicate fabrics.

' Further objects of' the invention are to provide a washing machine which is quick amlthorough in'itsacti'on and will enable large quantities of soiled clothes to be washed in a short period of time, which can be operated -without difficulty, and which has. no "delicate, parts which are liable to break or get out of repair.

with these and other ob ects in view. the invention consists in certain novel condunations and arrangements of the parts as will more. fully appear as the description proceeds, the novel ,t'eaturesthereof being 7 pointed out in' the appended claims.

For a full umlerstanding of' the invention,

reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation of a washing machine constructml in accordance with the invention.

Fig. 2 is a transverse vertical sectional view through the same.

Fig. 3 is a vertical sectional view taken on a lineuit right. angles to that of Fig. 2;

Fig. l is an enlarged sectional view through the rolling weight.

' Figs?) and 6 are detail views of the packing and clamping means belwcenlhe two sectionsof the hollow outer casing.

Corresponding and like parts are'referred to in the following description'and indicated inall the views of the drawings by the same reference characters; Y

Referring'to the; drawings. which illustrate one embodiment of the invention. the

numerals l and 2 designate the two complemental-halves of the hollow outer casing it of the washing machinegsaid casing having the general shape of a flattened Sphere so that across section taken in one direction is circnlar, as indicated by Fig. while across section taken at right anglesthereof is substantially ellipticahas indicated by Fig. 2.

Thelower half' 1 of the casing A larger tha'n'the upper half and is hollow or partially filled with hot soapy water into 'which tory t0. placing the upper section 2 of the casing in position. Trunnions 3 project from the flattened sides of the lower section' 1 of the casing and .areiaxially arranged the clothes to be washed are placed preparawith respect to the casing, said trunnionsbeing journaled in the upri ht standards Q of a supporting frame BT- ne of the trunn onsis shown as having 'a crank handle 5 applied thereto. while the other trunnion is provided with a pulley 6 by means of which power can be applied thereto if desired.

The meeting edges of the upper and lowersections 1 and '2 ofthe outer casing" are provided with corresponding outstanding- Ranges 7. one of the liangesbeing provided with an, annular packing ring 8 ()l jlllibol'ffl'l' like material which is substantially triangular in cross section and has the hasethermt' dovetailed at 9 into the flange. while the V-shaped edge of the packing ring projects outwardly from the flange and is adapted to be seated in a. correspondinglyshaped groove 10 in the other flange. Positioning pins 11 project from one of the flanges 7 and pass loosely through openings in the other fl'ange. said pins serving to hold the casing sections in proper relative position preparatory to tightening the clamps. The flange 7 of the lower casing section 1 is provided with a series of clamping hooks 12 which are adapted to extend around the flange 7 of the upper casing section. said clamping hooks being pivotally connected at 13 to levers it which are in turn pivotally connected at 15 to the flange 7 of the lower section 1. These operating levers ll have a cam action in connection with the clampe'o'v spring plungers j inwardly with e. 'n'zi'il' or suitable instrument, they "eah 'b'e' dis engiiged gether and u wziter-tight joint ohtaineglso 7 that the casing A cen'be turned about its axis without den or of leakage. I N The interior of the outer cafingn' is Fovided with an, annular racewayvwhic s concentric with the nxis'lipon which th'casing is pivoted. This .raceway issubstnn "tia'lly semicircuhir in cross section, as indiouted by Fig. 2,'and is 'provided with transverse corrugationsiw upon which theclo'thes.
